摘要： An object of the invention is to provide a core drill for drilling a fine hole which can securely fix an abrasive grain to a core material, can finish to a predetermined diameter in a relatively easy manner, and can manufacture one having a superfine diameter about some &mgr;m, and a method of manufacturing the same. A core drill for drilling a fine hole in accordance with the invention for achieving the object is structured such as to drill a fine hole onto a work, or grind an inner diameter of the drilled fine hole to a predetermined shape, and characterized by bundling ceramics long fibers so as to make a core material, impregnating the core material with a molten synthetic resin so as to harden, and holding an abrasive grain by the synthetic resin.

摘要： This improved rotary-type, super-abrasive grinding tool is designed to cope with a longstanding problem heretofore encountered when subjecting such tools to periodic dressing operations. The improved tool comprises an annular hub having a periphery or rim with a generally U-shaped slot therein, and a generally annularly-configured super-abrasive matrix supported in said slot and having an outer peripheral, configured working surface. The axially opposed walls of the slot buttress and support the sides of the super-abrasive matrix. Each of the walls have a plurality of peripherally-exposed, radially-disposed recesses therein containing a super-abrasive medium, preferably having the same composition and integral with the super-abrasive matrix. The exposed periphery of the super-abrasive medium protects peripherally-aligned portions of the rim from excessive wear when improperly contacted with the dressing medium.

摘要： An abrasive device is defined by a honeycomb or cellular structure which is configured to define the grinding device. The cells of the cellular structure are filled with the normal constituents that make up a grinding wheel such as abrasive grains, a bonding matrix such as an organic resin, and fillers. The bonding matrix acts to bond the abrasive grains together into a uniform mass. The bonding medium is also designed to bond the abrasive and fillers to the walls of the cellular structure.
